Function

The magnetic coil is the heart of an electromagnetic contactor. When voltage is applied to the coil's terminals, it creates a magnetic field. This field pulls a movable armature, which is mechanically linked to the contactor's main contacts. The movement of the armature closes the contacts, allowing current to flow to the connected load.

When the voltage is removed, the magnetic field collapses, and a spring returns the armature to its original position, opening the contacts and stopping the current flow. The Siemens 3RT2924-5AH21 coil performs this essential function with precision and reliability.
